    摘要: An authentication apparatus for a non-real-time IPTV system decrypts a first encrypted value included in a contents request message received from a device using a preset session key, and then verifies the validity of the contents request message. If the verification results of the contents request message are valid, the authentication apparatus encrypts a variation between timestamps of the authentication apparatus and the device using the session key, and then generates a second encrypted value. After verification information by which the device is capable of verifying the authentication apparatus has been generated using the second encrypted value, the authentication apparatus sends verification information, together with contents corresponding to the contents request message, to the device.

    摘要: Provided are a method for providing virtual private network (VPN) services to a mobile node (MN) in an IPv6 network and a gateway using the same. The method includes: performing IKE (Internet key exchange) negotiation with an MN (mobile node) which has performed handover, acquiring SA (security association) and then authenticating a terminal of the MN; receiving a BU (binding update) message from the MN and verifying the BU message, storing new position information of the MN, transmitting a BA (binding acknowledgement) message and performing mobility processing; if the mobility processing is completed, performing IPsec processing on packets which the MN transmits to a CN (correspondent node), and transmitting the packets; and re-configuring and transmitting packets so that packets which the CN transmits to a home address of the MN can be transmitted to a CoA (Care-of-Address) of the MN. A function performed by a home agent (HA) of Mobile IPv6 is performed so that IP mobility in VPN services can be provided and both mobility inside a VPN domain of the MN and mobility outside the VPN domain can be supported.

    摘要: A content sharing method performed in a content redistribution device based on a non-realtime IPTV service includes transmitting a secret key in password information of a user of the content redistribution device to an IPTV service server and storing a public key corresponding to the secret key; and transmitting an event message for content request to the IPTV service server to request a non-realtime IPTV service. Further, the content sharing method includes receiving contents requested in the event message for content requesting from the IPTV service server; and decoding the received contents and encrypting the decoded contents using the public key. Furthermore, the content sharing method includes transmitting the contents encrypted using the public key to content recipient devices; and generating an event message for content sharing using the public key to transmit the generated event message to the content recipient devices.

    摘要: There are provided an apparatus and method for transmitting data in a network system using network address translation. The method for transmitting data includes the steps of receiving a global network address corresponding to a local network address from a router using network address translation; encoding data using the global network address; and transmitting the encoded data to an external host on the global network via the router. Since the network address to be translated through the network address translation can be anticipated and substituted in real time during the transmission of the data, a variety of security services can be provided without significant modifications to the existing system, and accordingly, it is anticipated that the Internet protocol version 6 can be increasingly used.
